IMPROVEMENT IN SPARK-ARRESTE'RS.

vSpecificationforming part of Letters Patent N 0. l 84,706, dated November 28, 1876 ;v application filed August 28, 1 876.

To all whom it may concern Be it known that I, ANsoN W. FARRAND, of the city of Oshkosh, in the county of Winnebago and State of Wisconsin, have invented certain Improvements in Spark-Arresters,

of which the following is a specitication .My invention relates tok the use of an ingling plate or plates as a cover to the tank,

so constructed as to prevent the Water in the tank jfrom spattering over or being driven out by the draft, and also to prevent the passage of a spark that might escape the Water, and still allow a free escape to the smoke.

Figure l is a section of my invention. Fig. 2 is a plan of the tank, showing part of the tangling-plate removed.

C is the smoke-stack. The smoke and other products of combustion are turned by the inverted cone B, which is fixed inside of the smoke-stack, and are confined Within the flue A, over the top of which is the deflector D, which is turned down low enough inside to make sure of passing all the sparks into the Water. However, 4should a spark escape the ing for the-passage of the smoke. To renderY this tangler more absolutely secure, more than one plate may be used in its construcltion. I is the overlioW-pipe, and J is the discharge-pipe for emptying the tank. Both of these discharge into the Waste-pipe K. H is a pipe for conducting the Water from the purnp to the tank.

Having thus described my invention, what I claim as new, and desire to secure'by Letters Patent,is-

l. The Water-tank E, havingaspiral lip, F, and central overlloW-pipe I, in combination with the inverted cone B and deflector D, for the purpose of collecting and extinguishing the sparks, substantially as shown and described.

2. The spark-arrester consisting of theinverted cone B, fixed inside of the smoke-stack C of a steam-boiler, the detlector D, tank E, and tangling plate or plates Gr, all constructed and combined 'substantially as shown and described.
